Chem/IUPAC Name: Cellulose, carboxymethyl ether, sodium salt
COSING REF No: 32485
Cellulose Gum, also known as carboxymethyl cellulose (CMC) or sodium carboxymethyl cellulose, is a common ingredient used in cosmetics. It is a white or off-white powder that serves as a versatile additive in cosmetic formulations. Cellulose Gum is widely employed as a stabilizer, emulsifier, and thickening agent. Its presence in cosmetics helps to enhance product texture, viscosity, and overall performance. Cellulose Gum has excellent water-binding properties, contributing to improved hydration and moisture retention in skincare and hair care products. It is valued for its ability to create smooth and creamy formulations while providing stability and consistency. The chemical formula of Cellulose Gum is C8H15NaO8.

What is CELLULOSE GUM used for?

Cellulose Gum is a very useful ingredient in the personal care and cosmetic industry. It has a wide range of applications in different formulations.
  • Skin care: It is often included in moisturizers, lotions, and creams due to its excellent water-binding properties. Cellulose Gum helps to improve hydration by retaining moisture on the skin's surface, resulting in increased skin softness and suppleness. Additionally, it acts as a film-forming agent, providing a protective barrier that helps prevent moisture loss
  • Cosmetic products: It serves as a versatile ingredient. It is commonly used as a thickener and stabilizer in various formulations, such as creams, gels, and liquid foundations. It helps to create desirable textures, enhance product spreadability, and improve product adherence


Cellulose Gum is produced through a chemical process involving the reaction of cellulose with sodium hydroxide and chloroacetic acid. This reaction introduces carboxymethyl groups onto the cellulose structure, resulting in the formation of Cellulose Gum. The resulting product is then purified and used in the cosmetic industry.
